Magic Mouse 2 won't connect with MacBook Pro (mid 2012)

Amazingly this works:

1. Turn off wifi
2. Reconnect Magic Mouse
3. Turn on wifi again

Obviously a bug! Get it fixed Apple!

Thank you, thank you, thank you...that did the trick for me! Amazing, but it stopped 30 minutes of pulling my hair out! Thank you again!

I recently was ripping out my hair with a similar problem. My Magic Mouse 2 paired with my late 2009 27" iMac, which had worked fine before, would suddenly not work at all with the iMac. I also have a wireless keyboard which continued to work fine. And plugging in a USB mouse worked fine. In the end, the problem was that my son had paired my Magic Mouse 2 to our family MacBook Pro. It seems that when another Mac has control over your mouse, you won't be able to regain control of it on another Mac until you open the Bluetooth Preferences and "Disconnect" on the computer with which you do not want to use the mouse. That solved my problem completely.

Hello Sannefr,

Thank you for using Apple Support Communities.

I see you are having difficulties with your Magic Mouse 2 connecting to your MacBook Pro. It can be frustrating that a new device is not working as expected. The following article provides the basic troubleshooting to sort out what might be going on with the connection.

Hi, I am looking for solution.

I have a Macbook Pro 2011 running OS X EI Capitan.

Just bought a magic mouse 2 but I can't pair the devices up.

It didn't even show up at the bluetooth list.

I plugged in the mouse cable > system preference > mouse

Mouse is on, green can be seen.

Mouse battery level is also appeared.

But I just cant pair them.

Useless answer. That only takes you through the basics, doesn't answer the question of what happens when you've tried all that and it doesn't work. Typical Apple response. And you have to log in to find out it's of no help.

One answer is this...

Tells how to deal with the bug in Apple's Magic Mouse/MBP connection.
Pity you have to go to a third party...
Pity I had to waste half an hour just to use a mouse.

Thanks!
